Discretising Keyfitz' entropy for studies of actuarial senescence and comparative demography

2023

1. Keyfitz’ entropy is a widely used metric to quantify the shape of the survivorship curve of populations, from plants, to animals, and microbes. Keyfitz’ entropy values 1 correspond to species with a decreasing mortality rate with age (negative senescence), and a Keyfitz entropy of exactly 1 corresponds to a constant mortality rate with age. Keyfitz’ entropy was originally defined using a continuous-time model, and has since been discretised to facilitate its calculation from discrete-time demographic data. 2. Here, we show that the previously used discretisation of the continuous-time metric does not preserve the relationship with increasing, decreasing, or constant mortality rates. To r…

The Effect of an enriched sport program on children's executive functions: the ESA program

2020

Purpose: The effects of physical exercise on executive functions (EFs) are well documented. EFs are involved in daily activities, and their development determines the quality of people’s future life, both in terms of mental health and quality of life. The purpose of the current paper is to evaluate the effects of a physical education program, elaborated within the Enriched Sports Activity Program (ESA Program), an Erasmus + Project, on EFs, namely, visuospatial working memory, inhibitory control, cognitive flexibility, and task switching. Method: Data were collected on November 2017 (t1) and May 2018 (t2). At t1, a sample of 357 children from four European countries (Italy, Germany, Lithuan…

L2-L1 Translation Priming Effects in a Lexical Decision Task: Evidence From Low Proficient Korean-English Bilinguals

2018

One of the key issues in bilingual lexical representation is whether L1 processing is facilitated by L2 words. In this study, we conducted two experiments using the masked priming paradigm to examine how L2-L1 translation priming effects emerge when unbalanced, low proficiency, Korean-English bilinguals performed a lexical decision task. In Experiment 1, we used a 150 ms SOA (50 ms prime duration followed by a blank interval of 100 ms) and found a significant L2-L1 translation priming effect. In contrast, in Experiment 2, we used a 60 ms SOA (50 ms prime duration followed by a blank interval of 10 ms) and found a null effect of L2-L1 translation priming. This finding is the first demonstrat…

Analysis and Performance Evaluation of the IEEE 802.16 ARQ Mechanism

2008

The IEEE 802.16 standard defines the ARQ mechanismas a part of the MAC layer. The functioning of the ARQmechanism depends on a number of parameters. The IEEE802.16 specification defines them but it does not provide concrete values and solutions. This paper studies the key features and parameters of the 802.16 ARQ mechanism. In particular, we consider a choice for the ARQ feedback type, an algorithm to build block sequences, the ARQ feedback intensity, a scheduling of the ARQ feedbacks and retransmissions, the ARQ block rearrangement, ARQ transmission window and the ARQ block size. We ran simulation scenarios to study these parameters and how they impact the performance of application protoc…

Translating recent results from the Cardiovascular Outcomes Trials into clinical practice: recommendations from the Central and Eastern European Diab…

2017

Aims These recommendations aim to improve care for patients with type 2 diabetes (T2D) at high cardiovascular (CV) risk in Central and Eastern Europe. Cardiovascular disease (CVD) and/or chronic kidney disease (CKD) are major interdependent comorbidities in patients with T2D, accounting for 50% of mortality. Following recent CV outcomes trial (CVOT) results, including those from EMPA-REG OUTCOME®, LEADER®, SUSTAIN™-6 and, most recently, the CANVAS study, it is essential to develop regional expert consensus recommendations to aid physicians in interpreting these newest data to clinical practice. Methods The Central and Eastern European Diabetes Expert Group (CEEDEG) followed a Delphi method …

Utebarnehager – et sted for demokratisk praksis?

2013

The questions in the title is posed to discuss how an outdoor kindergarten space is contextualized and understood by those who are staying there. Nature is often seen as an especially open space, free from strong guidelines and structures. Being part of an educational practice gives the place new structures. The activities the children participate in and the employees expressed attitudes and practices are part of different discourses, which give certain limits or possibilities for what is going on at the Hut, and thus influence a democratic practice. Especially children’s play activities represent an opposition to the adult’s framing of the place. Democracy presupposes some frames, but if t…

Lexicographic studies in medicine: Academic Word List for clinical case histories

2013

Medical texts are often thought to pertain to a closed community, but how far the language used by that community overlaps with general academic lexis is unknown. We examined a corpus of clinical case histories using the software RANGE to characterise the lexis of clinical case histories quantitatively and present a wordlist for clinical medicine. Only 58% of the general academic wordlists are found in clinical texts but the 85% overlap with an important academic wordlist, the Coxhead 570, furnishes evidence for the academic nature of the lexis used for clinical cases in Medicine. There was little overlap (38%) between our clinical case wordlist and other wordlists of medical research artic…
